Ladybugs in Western Europe
Ladybugs are small, often colorfully decorated beetles found in many parts of the world, including Western Europe. They are not only aesthetically pleasing but also play a crucial role in the ecosystem.
Species of Ladybugs in Western Europe
There are many different species of ladybugs in Western Europe. Some of the most common species are the seven-spot ladybug, the two-spot ladybug, and the fourteen-spot ladybug. Each species has its unique features and preferences.
Lifecycle of the Ladybug
The lifecycle of the ladybug goes through four different developmental stages: egg, larva, pupa, and adult. The cycle starts when a female ladybug lays eggs on the underside of leaves or on stems near aphid colonies. After a few days, the larvae hatch from the eggs. These larvae are very voracious and consume numerous aphids during their development. After a few weeks and after several molts, the larvae pupate. The adult ladybug eventually emerges from the pupal case. Depending on the species and environmental conditions, the entire lifecycle can last between a month and a year.
Adalia bipunctata: The Two-Spot Ladybug
The two-spot ladybug, scientifically known as Adalia bipunctata, is one of the most common ladybugs in Western Europe. This beetle is often sold and used for biological pest control because of its preference for aphids.
Features of Adalia bipunctata:
- Size: approx. 3-5mm long
- Color: Usually red with two black spots, but there are also black variants with red spots
- Habitat: They prefer trees and shrubs but can also be found in gardens and fields
Using Adalia bipunctata for biological pest control offers the advantage of being a natural and eco-friendly method to combat pests like aphids without resorting to chemicals or pesticides.
At Biogrowi, you can buy Adalia bipunctata ladybug larvae per 50, 100, 200 or 300 larvae.
You can also choose to purchase the adult ladybugs instead. Adult ladybugs are a better choice than larvae when there are ants also present in the plants.
Role of Ladybugs in the Ecosystem of Western Europe
Ladybugs play a significant part in the ecosystem of Western Europe. They serve as natural pest controllers by consuming aphids and other harmful insects. This helps maintain the balance in the ecosystem and protects plants from pests.
Relationship Between Ladybugs and Ants
Ladybugs and ants share a remarkable and often complex relationship. Some ant species "milk" aphids for their sweet honeydew. Since aphids are a primary food source for ladybugs, there can be conflicts between ladybugs and ants. Ants often defend the aphids against ladybugs to secure their access to the honeydew. This protective mechanism of ants can influence the feeding behavior of ladybugs and hamper their ability for pest control. However, it's essential to note that not all species of ladybugs and ants share this kind of relationship.
Invasion of Ladybugs in Winter
During the colder months, ladybugs often seek shelter in homes and buildings to protect themselves from the winter weather. While they're generally harmless, they can appear in large numbers and be perceived as a nuisance.
It's crucial to note that ladybugs seeking shelter indoors usually don't cause damage and aren't toxic. They're merely looking for a warm place to overwinter. It's recommended to capture them gently and release them outside rather than killing them.
